3. When this switch is moved back to the ON position the sound will be immediately restored without waiting for the radio signal to be reinstated If the wireless system is not to be used for more than a few seconds it is preferable to slide the transmitter switch to the OFF position which mutes and deactivates the radio signal and powers down the transmitter Be sure to turn down the volume of the mixer or amplifier and then switch off the receiver Unplug signal leads from the receiver and mixer or amplifier when moving or packing away If the system is not to be used for long periods of time remove the batteries from the transmitter and unplug the power adapter from the receiver and the mains outlet Retracting the antennae can also help avoid damage when the system is not in use SPECIFICATIONS Carrier tyoe UHF 863 865MHz Frequency stabilit Maximum deviation Audio frequency response Signal to noise ratio Audio dynamic range T H D Maximum range Operating temperature De RECEIVER ee eee eee eee Power suppl Audio outputs XLR balanced Jack unbalanced Controls Indicators Power main RF and AF for each channel Dimensions Weight Pea a ee HANDHELD TRANSMITTER VH1 VH2 VHN2 a a Batter Switch RF emission Capsule type Dimensions Weight without battery aaa aa UP SOc PO PTT BELTPACK TRANSMITTER VN1 VN2 VHN2 VL1 Ee ee Se Batter Switch Connector Compatible microphones RF emission Dimen
4. n Turn microphone level s down on the receiver Note for dual sets with 2 transmitters both microphones outputs will be mixed and fed to both balanced and unbalanced outputs Connect the jack or XLR optional lead to the receiver s audio output connector turn down the volume of any equipment mixer amplifier etc that the signal will be fed into and then connect the jack or XLR to the equipment Warning take care not to point microphones towards speakers this can cause damaging feedback loud whistle or howling noise try to point microphones away from the speaker cabinets Move the switch on the handheld or beltpack transmitter to the first notch MUTE the LED should light momentarily If the LED stays on this is indicating that the battery is low or discharged Move on another notch ON and gradually increase the microphone level s on the receiver then increase the volume on the mixer or amplifier until the sound from the microphone can be heard through the equipment During use it may be useful for the reception of the microphone to be muted for a short period of time e g to avoid feedback when walking across the front of a speaker or avoid handling noise when placing the microphone down momentarily or adjusting a neckband microphone In these circumstances it may be better to move the transmitter switch to the MUTE position which maintains the radio frequency carrier signal but mutes the microphone input
5. ng immediately allow unit to dry out and have checked by qualified personnel before further use Avoid impact or heavy vibration to any of the components dropping the microphone can cause capsule failure No user serviceable parts inside transmitter or receiver refer servicing to qualified service personnel Safety G Ensure that the correct adapter is used with adequate current rating and that the mains voltage is as stated on the adapter G Avoid ingress of water or particles into the transmitter s or receiver e Use alkaline or NiMH batteries in the transmitter s and remove if unused for long periods Observe the correct polarity when replacing batteries Placement e Keep all components out of direct sunlight and away from heat sources G Do not place heavy objects on top of the receiver or transmitter s e If rack mounting secure the receiver to a 1U rack tray and do not place heavy equipment above the receiver Keep the transmitter s and receiver away from damp or dusty environments Cleaning Use a soft cloth with a neutral detergent to clean the body of the microphone transmitter and receiver o Lightly damp sterile wipes may be used on the microphone grille for hygiene purposes e To avoid damage do not use solvents to clean the components Handheld Transmitter Beltpack Transmitter UHF antenna LED power indicator Slide switch OFF MUTE ON 1 Windshield 2 Slide switch OFF MUTE ON 3 Battery compartment cover
